General Information:
Keywords: Oil Dielectric Strength Tester
Oil Breakdown Tester  
Transformer Oil Dielectric Strength Tester
EPOT-II conforms to international standard IEC-156, can be used for power frequency dielectric break down test on the transformer oil, capacitor oil, electric device, insulation tool, electric manufacturer and etc. It’s widely used in the fields of power system, petroleum, chemical industry, railway station, power station, electric manufacturer and etc.
EPOT series insulating oil dielectric strength tester is also known as oil breakdown voltage tester or oil BDV tester. Break down voltage is measured by observing at what voltage, sparking string between two electrodes immersed in the oil, separated by specific gap.
  • ◆ Self-detecting function. The regulator could return to zero start automatically.
  • ◆ Controlled a large capacity single chip microcomputer, which is stable and reliable.
  • ◆ The wide range watchdog circuit is set in the tester to prevent the crash.
  • ◆ The oil vessel is made of special glass by one-time casting to prevent the occurrence of oil leakage and interference.
  • ◆ The unique high-voltage sampling design allows the test value to enter the A / D converter directly, avoids the error caused in the analog circuit, and makes the measurement result more accurate
  • ◆ Full protection functions including over-current, over-voltage, short circuit to ensure the safety of operators. And has strong anti-interference ability and good electromagnetic compatibility
  • ◆ Build-in printer.
  • ◆ Automatic magnetic bar stir, to eliminate uneven and bubble of oil.
  • ◆ 100 test data storage, can display the ambient temperature and humidity.
  • ◆ Portable structure, easy to move, convenient for use indoor and outdoor.
